Site crews replacing 4T5503 machines usually want two things: a tip that fits without grinding and a wear rate they can predict. The 47-52 HRC body and 26.8 kg casting weight deliver both, batch after batch.

Tooth tips are individually wrapped and separated by cardboard to protect the cutting edge in transit, packed in bags or cartons depending on size, then palletised and strapped for forklift handling. Custom packing specifications are followed exactly as written.
